A Study Comparing Two Anti-inflammatory Medications Naproxen or Aspirin for Cancer Prevention in Lynch Syndrome

About the Study

The trial is enrolling people with . On average, the length of this study will last one year from the start of enrollment to completion. The study will measure  the effect of naproxen or aspirin on the immune cells in the gastrointestinal tract of people with . The trial will also evaluate any symptoms from the medications and any other changes of the colon and rectum.

What the Study Involves

This clinical trial is for people with who have no active cancer. People who have never had a cancer diagnosis may participate. People who have previously been diagnosed with cancer may participate if they completed treatment at least 6 months prior to joining the study, and they have enough of their colon and/or rectum remaining to undergo colonoscopy or sigmoidoscopy.  People will be randomly divided into one of two groups:

Group 1: People in this group will:

  • take two naproxen capsules by mouth once daily at approximately the same time each day.
  • have one procedure using (flexible sigmoidoscopy or colonoscopy) with biopsies.
  • 12 months later have a second procedure using flexible sigmoidoscopy.

Group 2: People in this group will:

  • take two aspirin capsules by mouth once daily at approximately the same time each day.
  • have one procedure using (flexible sigmoidoscopy or colonoscopy) with biopsies.
  • 12 months later have a second procedure using flexible sigmoidoscopy.
